Plan strenuous outdoor activities for early or late in the day when temperatures are cooler; then gradually build up tolerance for warmer conditions.

Take frequent breaks when working outdoors.

Wear a hat, sunscreen and light-colored, loose-fitting clothes when outdoors.

Eat more frequently but make sure meals are well-balanced and light.

Stay indoors in an air-conditioned environment as much as possible unless heat tolerance is well established. If air-conditioning is not available, lower window shades and use fans and cross-ventilation to cool rooms. If heat and humidity are extremely high, turn off fans or aim them through a window to blow the hot air out of the room.

Avoid dressing babies in heavy clothing or wrapping them in warm blankets.

At the first sign of heat illness (dizziness, nausea, headaches, muscle cramps) move to a cooler location, rest for a few minutes and slowly drink a cool beverage. Seek medical attention immediately if condition does not improve.

Check frequently on people who are elderly, ill or who may need help.

Make sure pets have plenty of water. Do not close them up in parked cars or hot buildings.
